How to give heat transfer coefficient input that varies with temperature?

Please login with a confirmed email address before reporting spam

I am trying to predict the steel member temperature after being exposed to 1300 °C. I gave thermal properties that vary with temperature as input in material properties. I gave a constant heat transfer coefficient value, But I cannot provide the heat transfer coefficient input that varies with temperature.

The temperature-dependent heat transfer coefficient(hc) expression is given by hc=0.0668T W/m2 °C 0<T<500 °C hc=0.231T-82.1 W/m2 °C T>500 °C (Ref: B Brickstad, B.L.Josefson)

How to give the heat transfer coefficient input that varies with temperature in heat transfer module? Please help me regarding this.

Thanks and regards Mahalingam C
